*** Cache is not at the posted coordinates ***
In order to find the final cache, you must use the images below to get information for three places that have a 3-digit number associated with it - A, B, and C. One of those numbers will take you to a place you do not want to go. Once that number has been eliminated, take the remaining 2 numbers and sutract them from the north and west posted coordinates respectively in the order in which they appear on this cache page.
